Wheels: Testing and Inspection
Wheel BalancingREPLACEMENT
STICK-ON TYPE BALANCE WEIGHT
1. Remove balance weights.
2. Using dynamic balancing, measure wheel balance.
3. Select a weight close to the value measured by dynamic balancing.
4. Install the selected weight to the point designated by dynamic balancing.
5. Using dynamic balancing, measure wheel balance again. Check that wheel balance is correctly adjusted.
Service limit: A
Balance weight for steel wheel, 2.16 mm (0.085 inch)
Balance weight for aluminum wheel, 4.5 mm (0.177 inch)
CAUTION:
^ Use genuine balance weights.
^ Balance weights are available for use with any of 14 to 16-inch wheels.
PASTE-ON TYPE BALANCE WEIGHT
1. Remove balance weights.
2. Remove traces of two-sided tape on wheel and clean adhesive layer.
3. Set balancing (dynamic balancing for stick-on balance weight is available) and measure wheel balance.
4. Multiply the measured weight by 1.6 to select a weight.
5. Select a weight close to the calculated value, clean the point designated by balancing and paste on the weight there.
Example of selecting balance weight:
Measured wheel balance: 34 g 34gx 1.6=54.4
Weight to be selected: 55g
CAUTION:
^ Press on the weight for more than 2 seconds with a force of 25 Nm (2.6 kgf-cm, 18 ft. lbs.) or more per 5 g to paste on.
^ Adjust weight balance from outside first and then inside.
^ The weight to be pasted on must be under 100 g.
INSPECTION
1. Proper wheel balance may be lost if the tire is repaired or if it wears. Check the tire for dynamic balance, and repair as necessary.
2. To check for dynamic balance, use a dynamic balancer. Drive in the balance weight on both the top and rear sides of the rim.
3. Some types of balancer can cause damage to the wheel. Use an appropriate balancer when adjusting the wheel balance.
